Interface MethodExecutor

public interface MethodExecutor

MethodExecutors are built by the resolvers and can be cached by the infrastructure to repeat an operation quickly
without going back to the resolvers. For example, the particular method to run on an object may be discovered by the
reflection method resolver - it will then build a MethodExecutor that executes that method and the MethodExecutor can
be reused without needing to go back to the resolver to discover the method again.

They can become stale, and in that case should throw an AccessException - this will cause the infrastructure to go
back to the resolvers to ask for a new one.
